Description

  The present invention relates to a medicine transfer device, and is suitable for a medicine transfer operation such as addition (mixed injection) of a medicine to a medicine bag such as an infusion bag in infusion.

In the case of infusion such as drip, another drug (second drug) such as a vitamin drug is stored in a drug bag (first drug container) in which a drug (first drug) such as glucose solution or physiological saline is stored. Injection (mixed injection) may be required. The infusion drug bag is formed into a bag-like body with a flexible film such as polyethylene, and includes a plug (first rubber stopper) formed of an elastic material such as rubber. It is configured to be sealed by an exhaust port. On the other hand, a mixed injection container (second drug container) for a drug to be mixed into a drug bag is configured as a rigid plastic molded body and has a rubber plug (second injection port) for sealing a needle-like injection port (mixed injection port). The rubber plug of the first drug container is punctured at the needle-like injection port of the second drug container while opening the second rubber plug, The second medicine is transferred (mixed injection) to the first medicine container through the needle-like injection port. As a transfer method of this type, the main body (cylindrical portion) of the needle-like inlet of the second drug container (mixed injection container) can be moved relative to the needle of the second drug container (mixed container) for mixed injection. The second rubber plug for sealing the second drug container is opened and the mixed injection operation is performed when puncturing the first injection hole into the first rubber plug for sealing the first drug container Has been proposed (Patent Document 1).

An embodiment of the drug delivery device of the present invention will be described. The drug injection device of this embodiment is an infusion bag (first drug container) in which a drug (first drug) such as glucose solution or physiological saline is stored. This is for injecting (mixed injection) another medicine (second medicine) such as a vitamin preparation. 1 and 2, the drug injection device includes a port main body 10 (first cylindrical main body of the present invention) and a needle-shaped main body 11 ( second cylindrical main body of the present invention). As will be described later, the port body 10 is connected to a plastic film soft container (second drug container) for storing the second drug to be mixed and injected. As will be described later, the needle-like main body 11 has a needle-like portion punctured by a rubber stopper of an infusion bag, and a medicine contained in a soft plastic film container is transferred (mixed injection) to the infusion bag.

  In FIGS. 1 and 2, the port body 10 is preferably formed of a hard plastic having sufficient rigidity to maintain its shape, and the material of the plastic is not limited to ABS (acrylonitrile- Styrene-butadiene copolymer), PP (polypropylene resin), PE (polyethylene resin), rigid PVC (hard vinyl chloride resin), PC (polycarbonate resin), COP (cyclic polyolefin resin), PS (polystyrene resin), acrylic resin And PET (polyethylene terephthalate resin). The port body 10 has a cylindrical shape as a whole, and forms a central flow path 12 extending in the axial direction. The central flow path 12 is opened while the one end 12-1 spaced from the needle-shaped body 11 is somewhat expanded, and the other end 12-2 adjacent to the needle-shaped body 11 is normally closed. In other words, the end surface of the port body 10 facing the needle-shaped body 11 has an upright surface on the lower half 14 from the diameter line, but the needle-shaped body 11 is formed by the relatively thin inclined surface 16 on the upper side from the diameter line. Some overhangs 10-1 are formed toward this side, and are connected to the uppermost upright surface 18 (see also FIG. 3). That is, the end face of the port body 10 facing the needle-like body 11 is formed by three portions 14, 16, and 18 that are formed on the side of the needle-like body 11 of the central flow path 12. The central channel 12 is closed on the side of the needle-shaped main body 11.

As shown in FIG. 3, the protruding portion 20 integrally extends from the inclined surface 16 in the orthogonal direction. Due to the inclination of the inclined surface 16, the protruding portion 20 does not face downward with respect to the axis of the port body 10 in FIG. , And extends beyond the end face portion 18 of the port body 10 closest to the needle-like body 11. Therefore, as will be described later, when the port main body 10 is fitted to the needle-shaped main body 11, the protrusion 20 is first engaged with the opposing surface of the needle-shaped main body 11, and is bent and biased downward in FIG. . Since the base inclined surface 16 of the protrusion 20 is thin, the base portion 22 is fragile, and the downward biasing force when the protrusion 20 is engaged with the opposing surface of the needle-like body 11. As a result, the protrusion 20 is broken at least on the bending side by the fragile portion 22. Therefore, the sealing at the end surface on the side of the needle-shaped main body 11 is broken at the broken portion, and the central flow path 12 is opened to the needle-shaped main body 11. The thin portion of the inclined surface 16 may be the entire circumference of the base of the protrusion 20 or may be partial, and by forming the inside of the protrusion 20 in a cavity, the entire circumference of the side surface of the protrusion 20 is formed. Or it can also be comprised in a partial thin part. Furthermore, it is also possible to form the thin-walled portion so by applying the cut, such as U-shape so as to easily break the protrusion 20.

  The port body 10 has an annular groove 24 formed on the outer periphery thereof, and an O-ring 26 is fitted into the annular groove 24, and the O-ring 26 seals the insertion portion between the port body 10 and the needle-like body 11. Further, the port body 10 is formed with positioning ribs 30 (positioning means of the present invention) that extend in the longitudinal direction from the annular flange portion 28 to the front of the annular groove 24 at the diameter opposite positions on the outer periphery. As will be described later, the rib 30 is fitted in the positioning groove of the needle-shaped main body 11 when the port main body 10 and the needle-shaped main body 11 are inserted together, thereby positioning the both members 10 and 11 in the rotational direction (rotation prevention). Achieve the function to do. The rib 30 has locking protrusions 32 on both side surfaces.

  Further, the port body 10 has a flat flange portion 34 formed on the open end portion 12-1 side of the central flow path 12, and the flat flange portion 34 is a plastic forming a soft container for containing a mixed injection drug. The film is sealed by thermocompression as described below.

  Next, the structure of the needle-shaped main body 11 will be described. The needle-shaped main body 11 is also preferably formed of a hard plastic having sufficient rigidity to maintain its shape, similar to the port main body 10. As in the case of the port body 10, there is no limitation, but ABS (acrylonitrile-styrene-butadiene copolymer), PP (polypropylene resin), PE (polyethylene resin), hard PVC (hard vinyl chloride resin), PC (Polycarbonate resin), COP (cyclic polyolefin resin), PS (polystyrene resin), acrylic resin, PET (polyethylene terephthalate resin), and the like. The needle-shaped main body 11 has a cylindrical shape as a whole and has a central flow path 40 extending in the axial direction. One end 40-1 on the side of the port main body 10 is opened straight, and the front end portion of the port main body 10 is fitted and attached to the opening as described later. The other end 40-2 of the central flow path 40 of the needle-shaped main body 11 extends to the needle-shaped portion 42, and the inner diameter of the central flow path 40-2 is reduced in the needle-shaped portion 42, and the tip of the needle-shaped portion 42 is sharpened. The central channel 40-2 is open to the outside through the side hole 46 at a position slightly before the portion 42-1. As will be described later, at the time of mixed injection, the medicine from the mixed injection container is transferred and mixed into the infusion bag from the side hole 46.

The straight hole portion of the central flow path 40 of the needle-shaped body 11 is a pair of portions 48 slightly raised from the bottom surface 40-3 of the straight hole portion with the longitudinal center line of the central flow path 40 interposed therebetween (see FIG. 5). The raised portion 48 remains at the edges 48-1 and 48-2 that intersect at 90 degrees, and the diametrical groove 50 (the recess of the present invention) between the opposed edges 48-2 of the raised portion 48. The bottom surface 40-3 side of the straight edge 48-1 has a depression 51. The width of the groove 50 is somewhat wider than the diameter of the protrusion 20 of the port body 10. When the port body 10 is pushed deeply into the needle-like body 11 for the mixed injection operation, the first pushing operation is performed. In the process, the protrusion 20 can be reliably accommodated in the groove 50, and when the protrusion 20 is broken at the fragile portion 22 by being pushed to the limit, the protrusion 20 is completely accommodated and held in the groove 50. The dead space can be made as small as possible, and the medicine in the mixed injection container can be transferred to the infusion bag without waste.

  As shown in FIG. 1, the needle-like main body 11 has an annular groove 54 formed on the outer peripheral surface close to the needle-like portion 42, and an O-ring 56 is attached to the annular groove 54. Is for sealing when the needle cap 58 (FIG. 6) is attached. Further, the needle-like main body 11 has a pair of U-shaped guides 60 at the outer diameter opposing positions near the open end surface on the side away from the needle-like portion 42. As shown in FIG. 2, each U-shaped guide 60 has a U-shaped cross-sectional shape, and a guide groove 62 that opens toward the port body 10 is formed inside the U-shaped guide 60. Ten guide ribs 30 can be inserted. As shown in FIG. 2, each guide groove 62 has two tapered surfaces 62-1 and 62-2 on each of the opposing surfaces, and locking protrusions at the ends of the respective tapered surfaces 62-1 and 62-2. The parts 62A and 62B are provided. As will be described later, by selectively engaging the locking protrusions 32A and 62B with the locking protrusion 32 of the guide rib 30 on the port body 10 side, the insertion depth of the port body 10 with respect to the needle-shaped body 11 is sealed. It can be locked in two stages: a stopped state (assembled state but not used) and a pushed-in state (during mixed medicine).

  The material of the O-rings 26 and 56 is not particularly limited, but is preferably an elastic body. As such an elastic body, a polymer elastomer such as a styrene elastomer, an olefin elastomer, a polyester elastomer, or a nylon elastomer may be used from a rubber made of silicon rubber, butyl rubber, isoprene rubber, natural rubber or the like. Good.

Next, the usage mode in the case where the pharmaceutical injection device of the embodiment of the present invention described above is used for co-infusion with an infusion bag will be described. The assembled state of the port main body 10 and the needle-shaped main body 11 is shown in FIGS. The closed end of the port body 10 is inserted into the opening 40-1 on the rear end side of the needle-like body 11. In this insertion process, the positioning of the port body 10 and the needle-shaped body 11 in the rotational direction is performed so that the positioning rib 30 on the port body 10 side and the guide groove 62 on the port body 10 side are aligned with each other. The overhanging portion 10-1 of the needle-like main body 11 is made to face the hollow portion 51 of the needle-like main body 11. When the port body 10 is pushed into the needle-like body 11 in such an alignment state, the positioning rib 30 on the port body 10 side is inserted into the guide groove 62 on the needle-like body 11 side. By deepening the insertion into the main body 11, the locking protrusion 32 of the positioning rib 30 gets over the first locking protrusion 62A via the first tapered surface 62-2 of the guide groove 62. FIG. Is obtained. In this state, the locking protrusion 32 of the positioning rib 30 engages with the base portion (the recessed portion) of the second tapered surface 62-1. Therefore, the port main body 10 and the needle-shaped main body 11 are locked under elastic force in the axial positional relationship (assembled state) shown in FIGS. 6 and 7. In this assembled state, as shown in FIG. 6, the fragile protrusion 20 at the tip of the port body 10 is spaced from the opposed bottom surface 40-3 of the cylindrical hole of the needle-like body 11 so as to face the groove between the raised portions 48. The fragile protrusion 20 is located and remains in an integrally molded state with the remaining portion of the port body 10, that is, the thin inclined surface 16 (FIG. 3). Therefore, the center flow path 12 of the port body 10 maintains a closed state at the end 12-2 on the needle-like body 11 side. Then, a needle cap 58 is attached.

In the assembled state of the port main body 10 and the needle-shaped main body 11 shown in FIGS. 6 and 7, a soft container for co-infusion and formation of a medicine are performed. That is, the upper and lower plastic films are combined and formed into a bag shape (soft container) by thermocompression of the outer periphery. The soft container 80 formed in this way is partially shown in FIG. 6, and the soft container 80 includes a seal portion (thermocompression bonding portion of a plastic film) 82 on the outer periphery. The soft container 80 is formed so that the outer periphery is partially unsealed and opened, the flat flange portion 34 of the port body 10 is inserted into the opening, and the plastic film forming the soft container 80 is flattened with the flat flange. It can be thermally welded to the outer peripheral surface of the portion 34. In this state, the filling and sealing of the medicine into the hollow portion 84 of the soft container 80 is performed as is well known, and the medicine injection portion, that is, the port body 10 and the needle-like body 11 is mounted, and the needle-like portion 42 is such co-infusion container assembly of Figure 6 with the infusion part and the flexible container Ru formed by mounting the needle cap 58 is completed.

  Next, the mixed injection operation by the mixed injection container assembly of FIG. 6 will be described. In FIG. 8, the drip bag 90 is formed in a bag shape by thermocompression bonding of the peripheral portion 92 of the two plastic films stacked as is well known. 94, a drip medicine such as glucose solution or physiological saline is accommodated, and a port member 96 is fixed to a predetermined portion of the peripheral portion 92 which is thermocompression bonded. The port member 96 is a molded product made of a plastic material having a cylindrical shape, and a plug 98 made of an elastic material such as rubber is attached to the outer end portion of the port member 96. In order to infuse (transfer) the medicine in the soft container 80 into the infusion bag 90, the needle-like portion 42 is punctured into the rubber stopper 98 of the infusion bag 90 by pushing the infusion container assembly. The sliding resistance between the port main body 10 and the needle-shaped main body 11 is set so that the needle-shaped portion 42 is larger than the resistance force for puncturing the rubber plug 98. Various factors such as fitting, needle shape and needle surface processing are adjusted. Therefore, as shown in FIG. 8, the relative position of the port main body 10 and the needle-shaped main body 11 as shown in FIG. -3) is maintained. Therefore, the closed state of the end 12-2 of the central flow path 12, in other words, the sealed state of the medicine in the soft container 80 is maintained, and the medicine in the soft container 80 leaks out during puncturing. There is nothing.

  Even after the needle-like portion 42 is completely punctured into the rubber stopper 98 as shown in FIG. 8, the port body 10 overcomes the sliding resistance with the needle-like body 11 by continuing to push in the mixed injection container assembly. Relative sliding with respect to the main body 11, and in the course of this sliding, the projection 20 at the tip of the port main body 10 is brought into contact with the facing surface 40-3 of the needle-shaped main body 11 through the groove 50 between the raised portions 48. The protrusion 20 is applied with a downward bending force due to the downward inclination in FIG. 6 and is broken at the weak root portion 22 due to its thinness. Even if the breakage always occurs on the bending side, but the unit is maintained on the other side, there is no problem in the opening function due to the breakage. FIG. 8 shows a state in which the port body 10 and the needle-like body 11 are completely pushed so as to come into contact with each other between the opposing surfaces, and the protrusion 20 takes an upright state and is accommodated in the groove 50 between the raised portions 48. . 8, the locking projection 32 in FIG. 7 passes over the second locking projection 62B via the second tapered surface 62-2 of the guide groove 62, and the projections 32, 62B By the engagement, the relative position (opened state) of FIG. 8 between the port main body 10 and the needle-shaped main body 11 is maintained under elastic force. 3 is broken by the breakage of the protrusion 20, and the central flow path 12 of the port body 10 is needle-like through the opening 89 formed in the inclined surface 16 by the breakage of the protrusion 20. It is connected to the central flow paths 40, 40-2 of the main body 11. Therefore, the medicine in the soft container 80 is transferred into the drip bag 90 from the side hole 46 through the central flow paths 12, 12-2, 40 and 40-2.

  In the above configuration, when the projection 20 is pushed until the projection 20 is broken, the locking projection 32 gets over the second-stage locking projection 62B (FIG. 7), and at this time, a clicking sound is generated. This is an audible confirmation means for confirming to the operator that the push-in operation up to the release of the sealed state has been completed. In addition to this, a visual confirmation means can be provided so that an unskilled one does not cause an erroneous operation in confirming the indentation depth. In the above embodiment, the gap between the annular flange 28 on the port main body 10 side and the guide rib 30 on the needle-shaped main body 11 side can be eliminated just when the projection 20 is pushed to break. 0 can be used as a confirmation or indicator that a predetermined indentation depth has been obtained.

  FIG. 9 shows a means for confirming the completion of the pushing operation in another embodiment. In this embodiment, a protrusion 30A is provided on the guide rib 30 of the port body 10, and a protrusion 60A is provided on the U-shaped guide 60 of the needle-like body 11. Can do. The protrusions 30A and 60B are separated in the normal state (when not opened (when the protrusion 20 is not broken)) shown in FIG. 9 (a), but when opened (when the protrusion 20 is broken), FIG. Since the protrusions 30A and 60B are aligned as shown in FIG. 4, the confirmation operation of the depth of pressing between the port main body 10 and the needle-shaped main body 11 for opening becomes easy and reliable.

  FIG. 10 shows another embodiment of the indentation depth confirmation means, which is an example in which a transparent seam is provided. That is, the port main body 10 forms a transparent band 70 in the circumferential direction of the cylindrical portion 10 ′ inserted into the needle-shaped main body 11, and the other policy-shaped main body 11 is inserted with the cylindrical portion 10 ′ of the port main body 10. The cylindrical portion 11 ′ has a circumferential transparent band 72. In portions other than the transparent bands 70 and 72, the port main body 10 and the needle-shaped main body 11 are subjected to printing, labeling, and graining (roughening) so as to be opaque. The transparent belts 70 and 72 are spaced apart and do not overlap in the normal state (when unopened (when the protrusion 20 is not broken)) shown in FIG. 10 (a), but the whole is not transparent, but when opened (when the protrusion 20 is broken) As shown in FIG. 10 (b), since the transparent bands 70 and 72 overlap each other, the whole can be seen through, and this is an indicator that a predetermined depth has been pushed.

  In the embodiment of FIG. 10, a modified embodiment in which an appropriate character (for example, “open” or “Open”) is engraved on the band-like region 70 (which may not be transparent in this case) of the port body 10 is also possible. is there. The band-like portions 70 and 72 are separated in the normal state (when unopened (when the protrusion 20 is not broken)) shown in FIG. 10 (a) and do not overlap, so the band-like region 70 of the port body 10 is an opaque needle located on the upper side. It is shielded by the main body 11 and the characters “open” and “Open” cannot be seen. However, at the time of opening (when the protrusion 20 is broken), as shown in FIG. 10 (B), the band-like portions 70 and 72 overlap each other, so that “open” or “Open” stamped on the belt-like portion 70 of the lower port body 10 is provided. Since the character "" can be seen through the transparent belt-like portion 72 of the upper needle-like main body 11, it can be used as an indicator that a predetermined depth has been pushed.

  FIG. 11 shows still another embodiment of the indentation depth confirmation means. The port main body 10 is provided with an identification portion 74 that is normally opened but is closed at the time of opening. That is, the identification part 74 is a symbol or a line such as a character indicating a closed state (for example, “unopened” or “Close”), and is provided in the vicinity of the flange part 28. (When not opened (when the protrusion 20 is not broken)), since the flange portion 28 is separated from the end surface of the needle-like main body 11, the identification portion 74 is exposed to the outside, and “unopened” or “Close” is operated. It can be visually recognized by employees. At the time of opening (when the protrusion 20 is broken), characters and lines such as “unopened” or “Close” of the identification portion 74 are closed by the opaque needle-like body 11 and cannot be visually recognized as shown in FIG. Therefore, it can be used as an indicator that a predetermined depth has been pushed.

  FIG. 12 shows still another embodiment of the indentation depth confirmation means. In this embodiment, confirmation is performed by line coincidence / non-coincidence. That is, the first coincidence determination line 76 is engraved on the peripheral surface of the port main body 10, and the second coincidence determination line 78 is imprinted on the needle-like main body 11 with the slit 11 </ b> B at the end face interposed therebetween. In the normal state (when unopened (when the protrusion 20 is not broken)) shown in FIG.
